Excellent movie for the Teen/Preteen set. It sets out to teach lessons in cooperation, ethics, etc. At about 10-15 minutes into the show I was ready to turn it off, it was getting so boring and going nowhere. Once the physics teacher got more into the picture, the plot began to hold together. The science was basically a means to an end. I doubt high school physics could teach these youngsters how to build what they did, even with the added "resources" the teens had available to them and what their grandmother tried to downplay.

A "feel good" movie for the family, but not in the same league as "Star Trek" and other television sci-fi.
